CGQPER, OF EDGEWOOD, RHODE ISLAND, ASSIGNOR TO PILGRIM PLUSH COMPANY, OF PROVIDENCE, RHODE ISLAND, A CORPORATION OF RHODE ISLAND PLUSH FABRIC Application filed January 9, 1930. Serial No. 419,579..

This invention relates to an improved con-- struotion of woven pile fabric and method of forming the same; and has for its object to provide an improved construction of pile :fabric having a so-called fast pile weave or one in which the pile tufts are securely locked in the ground fabric, the fabric being woven with the minimum number of pick threads to produce a high class pile fabric,

sespecially mohair plush suitable for upholstery and other purposes.

A further object of the invention is to so arrange the pile tufts in the fabric that crosswise lines in the face of the fabric will be avoided;

'With these and other objects in view, the

invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings:

Fig. 1 is an enlarged View of the face of the fabric, showing the arrangement of the different threads therein.

Fig. 2 is a section on the line 22 of Fig. 1.

Fig. 3 is a section on the line 3-3 of Fig. 1.

Fig. 4 is a perspective view showing the pile threads as interlaced with the pick threads of both ground fabrics; also showing the ground warp threads as binding the pile threads in the upper ground fabric.

Fig. 5 shows an edge view of the vile fabric formed with two spaced ground abrics connected by the pile threads, a portion of the pile threads being severed to form plush fabric having upstanding tufts on its ace.

Fig. 6 is a detailed view showing one of the W-shaped tufts.

In the construction of plush or pile fabric, the number of pile tufts on the face of the cloth in any given area represents the value Jof the plush, hence it will be obvious that Where it is possible to obtain the same number of pile tufts, with a reduction of picks, without deteriorating the face value of the cloth a real saving is effected.

By employing my improved method of forming pile fabric, I obtain the maximum number of tufts by the use of the minimum number of picks and to facilitate weaving sucha fabric, I preferably first form the fabric double, that is, with two spaced ground fabrics connected by the pile threads of each ground which threads are woven alternately over and under three successive pick threads in its ground and then each is led across to engage the next adjacent successive pick threadin the opposite ground, by which construction it will be seen that no pick thread in either ground is skipped but every one has a pile thread looped about it, thus minimizing the number of pick threads employed. I

In order to avoid a crosswise line effect in the face of the tufted fabric, I preferablyemploy three dents of pileto arepeat of the weaving pattern, each dent carrying a group of one pile thread and two binding warp threads, and bythis means I obtain with each six picksran d three dents, a complete cycleof the weave pattern which secures the desired even face appearance. The loop #5:.- portion of the different pile tufts thus fabrics and .thesevered upstanding ends form the tuftsin each ground; and the following is a detailed description of the present embodiment of my invention and show, ing means by which this advantageous result may be accomplished With reference to the drawings, 8 and 9 designate the two opposite background fabrics, and 10 designates the pick threads; 11 the pile threads and 12 the two warp threads which are woven into the background fabrics 8 and 9. In'the weaving of my improved fabric, two ground warp threads 12 and a. pile thread .11 are threaded through each reed dent (not shown) for each of the different ground fabrics, the pile threads 11 in the opposite grounds are then preferably woven alternately over and under the first three pick threads 10 and then led across as at 13 into the opposite ground, each to be looped over the fourth, or neXt adjacent pick 5 thread, whereby no pick thread remains unused for the support of a pile thread loop. In order to tie the loop portion of the pile thread tufts into its background, I weave the two background warp threads 12 of each dent alternatelyand oppositely over one and under two and then under one and over two of the pick threads, which result may be accomplished in the loom by the use of a suit able number of extra heddles and cams.

In order to avoid crosswise line effect in the face of the fabric, I preferably employ three dents of pile threads for a repeat, as shown in Fig. 1, in which the three pile threads a, 7) and 0 form a cycle; pile thread 2&6 being advanced one pick and pile 0 two picks beyond pile a, after which the pattern is repeated thus forming a diagonal weave which effectually avoids the straight line effects across the face of the fabric. After 2 the fabric is formed the crossing pile threads aresevere'd at 13, the severed ends upstanding from the face of its background forming the pile tufts 14, which with its loop portion is interwoven with three successive pick Wthreadsresembles the letterW. By this arrangement of pick and pile threads, I am enabled to obtain eighteen tufts of pile with each eighteen picks and three dents and by my improved method of weaving pile fabric I obtain a high grade plush with its tufts closely set together and securely locked or anchored into its ground fabric to form a fast pile secured by the minimum number of picks and as the capacity of a loom is -measured by its number of picks per unit of time, it will be seen that by using the minimum number of picks I obtainthe maximum loom capacity.

Having thus described one illustrative embodiment of my invention and the best mode known to me for carrying out my method, I desire it to be understood that although specific terms are employed, they are used in a generic and descriptive sense and not for the purpose of limitation, the scope of the invention being defined and lim ited only by the terms of the appended claims.

.I claim:

1. A method of weaving pile fabric with twospace'd ground fabrics, which consists in interlacing the pile threads of each dent in each ground fabric alternately over and under three-successive picks with its ground fabric then leading these pile threads diagonall'y across and similarly interlacing them with the next three succeeding pick threads thread being oppositely and alternately interwoven over one and under two pick threads into each ground fabric, successively advancing the crossing one pick thread, and severing the pile threads extending between the two ground fabrics to form tufts, whereby said tufts are arranged in cycles diagonally across the fabric, the tufts in each succeeding group in each cycle being advanced one pick for each predetermined number of dents before repeating to prevent the forming of continuous lines across the face of the fabric.

2. A woven cut pile'fabric comprising a ground fabric having pick threads extending therethrough, pile tufts each having two ends upstanding from the ground fabric,

the loop portion ofeach tuft being inter woven with each successive group of three pick threads, and a pair of binding warp threads to each pile thread interwoven with the pick threads, said tufts being arranged in cycles, those in each cycle being each advanced one pick thread for each three successive dents and then repeating to form a diagonal weave, the ends of two pile threads being disposed in the spaces between successive pick threads.

In testimony whereof I affix my signature.
